Tempo analysis.
Even though the Bob Dylan version and the Eric clapton version have a much slower feel that the Guns ’n Roses version, the tempograms do not seem to differ to much in BPM. I have tried verifying the tempo’s through Google because of this reason. The tempo estimations for the Bob Dylan version and the Guns ’n roses version seem to vary rather much somewhere between 65 and 140 bpm, however for the Eric Clapton version they seem pretty consistent. Which I thought was interesting considering this shows two pretty strong tempo “powers”. Something else I think is interesting to note is the tempo increase in the beginning and tempo decrease at the end in the Guns ’n Roses version, this change is clearly audible, which to me might be an indication that the estimations are rather accurate. Nonetheless these tempo estimations shown here are an interesting indication that the tempo more or less remained the same over the differnet cover versions.
Novelty
Even though the grids vary (pay attention to different x and y scales), the degree of novelty does not seem to differ significantly between the versions. We see one outlier in the guns n roses graph that seems to marginalize the other values around 240. This is a little spike after a silent part, where they start singing “knock knock knocking” again. Other than that we see in general novelties with a maximum of 15. Especially in the Eric Clapton version. Which is expected since this is a rather consistent song.

Plot tab
For my first representation I have tried to create an overview of the different versions of cover songs in my Corpus. Sadly I have had some trouble getting the artists names from Spotify which made me unable to give information about this. Even a more major issue I faced was the group_by function, which can only group songs that have the exact same title. Cover songs sadly do not always have exctly the same title. In the graph below you see an attempt to show a basic distribution of my Corpus based on the energy (x-axis) and valence (y-axis). I chose these two values to give an insight in the overal feel of a song according to spotify. With this I attempted to create a feeling of how far the feel of the cover songs was apart from the original (and possibly other covers of the same song), to give a stronger sense of the differences I attempted to draw lines between different versions of the same song. It is visble that I still struggle with correct imlementation, I seem to lose colors and visibility now I have corrected the issue with the song names.
Wavferform tab
As you can see ive included my waveform comparisons between different versions of Knocking on heavens door. I’ve chosen this one, because it shows absolutely no similarity what so ever. For the Bob Dylan version this makes sense as it is significantly shorter than the other version. However, the Eric Clapton version and the Guns ’N Roses version are very similar in duration. I think this is a very interesting representation on how different the “same” songs can be. I will try to show this more with graphs in the future, as making waveform analysis for all songs is not feasible nor informative. I tried showing them in a rows overview, which is nicer, however because of the code that is shown this really messes up the overview.

The guns n roses version has the most varriation in it, and actually sounds “biggest”. The clapton verson is much more calm and steady. Where the Dylan version is actual pretty quite and steady. Which is since its much smaller length also to be expected.
Some chords
Some chords
I am currently working on a different way to extract the most dominant/stronger occuring chords from a variaty of sorts. If I manage this I will include this here, otherwise some extra chords graphs will be added from a variety of songs from the corpus.
